Stereochemical Studies. V. Structure of the 'Hydroxymethylene Derivative' Obtained from trans-Decahydronaphthalen-1-one. A Spectroscopic Study

Abstract

Formylation of trans-decahydronaphthalen-1-one gives a 'hydroxymethylene derivative' which is, in reality, a complex mixture of stereoisomeric and tautomeric structures; stereochemical integrity at the ring junction is lost during the reaction. The same 'derivative' is obtained on formylation of the isomeric cis-ketone.
